Methods and systems described herein facilitate offload processing of encapsulated packets. A virtualization manager enables a virtual switch to be associated with a virtual overlay network. A virtual machine includes a virtual NIC that is connected to the virtual overlay network via the virtual switch. The virtualization manager is configured to encapsulate an outgoing packet sent from the virtual machine to the virtual overlay network. The virtualization manager is also configured to de-encapsulate an incoming packet sent from the virtual overlay network to the virtual machine. A physical NIC is configured to calculate at least one inner checksum based on the encapsulated outgoing packet and to verify at least one inner checksum included in the de-encapsulated incoming packet.
